Y

One of the objects of the invention is the provision of a co-aXial disk spectrum selectorembodying yin two disks, the complete solar spectrum including primary and secondary colors."

Another of my objects is the provision of a device including two rotatably adjustable disks so arranged that either or both of the disks may be quickly adjusted into alignment with the source of light. a

Another object which 1 have in view is the provision of a disk arrangement which completely eliminates all handling of color slides.

I also contemplate the provision of a suit- 20 able lens whereby the light maybe ldiffused or concentrated at will without increasing or decreasing the distance of the source of light from the body member being treated.

Another of my objects is the provision of a rotatably adjustable disk with a springV latching'device for maintaining the disk in perfect alignment with the source of light, this positively eliminating the possibility of having obj the device.

It is also my object to provide an instrument which is light in weight and which is easily portable and in which all thecolors arerepresented so that there is no possibility of leaving some of the colors behind when answering a call.

It is also my object to provide two disks each of which has a plurality of colored Windows with one space left open so that the complete spectrum is available without the filtering eii'ect of color disks.

Having in view these objects and others which will be pointed out in the following description, l will now refer to the drawing,

in which Figure 1 is a view in side elevation of the co-axial disk spectrum selector.

Figure 2 is a view in rear elevation of the co-aXial disk spectrum selector.

one of the disks and showing also the automatic latching mechanism.

Figure 4 is a detail view showing a fragment of one of the disks and showing also a sectioned fragment of the latching bar, the iigure showing particularly the structure of the latch within the latching bar.

Figure 5 is a diagrammatic view in side elevation of the co-aXial disk spectrum selector and showing also the assembly with the lamp. i j The lamp is of the arc type in which two carbons 10 and 11 are employed. VThe lamp is provided with a goose neck 12k whereby the entire assembly. may be adjustably secured to a stand or to an article of furniture. The lamp is also provided with a casing having a Hue 13 and having also a sleeve portion 14 for conducting the beam of light.

My device includes a funnel 15 having set screws 16, 'the funnel being so dimensioned that it will slip easily over the sleeve 14 to which it may be iirmly secured by means of the set screws 16. The funnel '15 provides a passage way for the beam of light from the source of light at the junction of the carbons 10 and 11. Projecting upwardly from the funnel 15 and integral therewith is a support 17 having an aperture for receiving the rod 18. The upper surface of Y the rod 18 is flattened as best shown in Figure 3 and the rod is firmly secured to the funnel by means of the set screw 19 :passing through theupper surface of the 4support 17. The rod 18 constitutes a support for other parts of the spectrum selector as will be'explained subsequently. Y

, Projecting downwardly from the funnel 15 is an ear 20 which is` also integral with thefunnel 15. The ear 2O is provided in its lower end portion with an aperture for receiving a pivot 21 which is vpreferably in the form of a bolt. Two disks 22 and 23 are carried on. the pivot 21. The two disks are exactly alike in their form and both are centrally apertured asV shown in Figure 3 for receiving the pivot pin 21. VBoth disks are provided with a plurality of apertures 24, the number7 size, and position of the apertures 24 being alike in both disks and being also symmetrical with respect to the disk in which they are formed. These apertures are also so positioned that they may be brought successively into alignment with the smaller end of the funnel 15.

For adjustably latching the disks'22 and 23 with apertures in registration with each other and with the` smaller end of the funnel l5, eaclmdisk` is provided `with a plurality of notches 25, these notches being 1n the peripheries of the disks and at points midway between successive apertures 24. The latching bar 26 is secured byY means of a set screw 27 to the supporting rod 18. The lower surface of the Vlat-ching bar 26 is arcuate in form and substantially in contact with the disks 22 andv 23, there being just enough clearance to prevent interference of the latching bar with the disks during the rotation thereof. Near the outer eX- tremity of the latching bar 26 is an aperture which is best shown in Figure 4. The upperV portion of this' aperturek is screw threaded for the reception of ascrew plug 28. vThe screw plug is designed to hold and to tension a coil spring 29 seated against a ball bearing 30. The tension of the `spring .e 29 maybe increased or decreased by tighten- The ing or loosening the screw plug 28.

j ball bearing 30 seats readily into'any one ofthe sockets or notches 25 so that the disks will automatically latch when the .ball 30 drops into a notch 25.

The light passing through the funnel'l and through a pair of apertures 24 reaches the projecting lens 3l.' This lens is supported on a member 32 which ingturnisv supported' on the rod 18, the securing means being in the form of' a set screw 33 which bears yagainst the flattened surface of the rod 18. The set screw 33 makes it possible to shift the member 32 along/the rod 18 so as to vary the distance oi the projecting lens 3l from the apertures'of the disk 22. This adjustment, together with the adjustments in the lens combination itself, makes it possible to secure any desired degree of' concentration or diffusion of the light.

Y The apertures 24 are provid-ed with light lilters of various colors, one of the apertures 24 in each disk being either left openY or provided with arwindow of clear glass or other suitable transparent material.

Since' both disks 22 and 23 are rotatable, it is possible thus to bring any two light com-Y binations into registration with each otherV and with the light source.

The carbons employed in color therapy are now obtainable in a considerable variety for emitting light rays confined within a limited portion of either the visible or invisible spectrum. The proper selection of carbon must, of course, bemade in the use ofA my device;k Any of'these carbons will,

light rays Within a very limited portion of spectrum and to thus eliminate the error which follows from the use of an instrument in which undesired light rays are permitted to. pass through. y

From the foregoing description it will be apparent that I have provided a spectrum selector for primary and secondary colors and for light rays in the ultra-violet and infra-red portions of the invisible spectrum. It will also be apparent that the device is of great simplicity in use since the adjustment may be quickly and easily made land in which the disks are yieldablylatched by means of a simple automatic latch. The color disks are part of the instrument and Vthey require no handlingl in .use as is the case with detachable color slides which are also. apt to be mislaid and forgotten when the device is taken along in answeringa call. It is evident also that the instrument as a whole is very light in weight and that for this reason it is easily portable. Y

In my drawing I have shown vthe disks' a great range over practically the entire Y spectrum but italso has great selectivity, giving the' operator full control over the sedative blues and violets, the stabilizing greens, the intestinal and renal4 energizing yellows and the stimulating reds. With my device tense tissues may be relaxed and inflammations may be quickly relieved so that it enables the operator to manipulate sore muscles or to adjust painful joints with little or' no pain to the patient.

Having thus described my invention in such full, clear, and exact Yterms that its construction and operation ywill be readily understood by others skilled inthe art to which it pertains, what I claim as new and desire toV secure by Letters Patent of the United Statesis: v

In a color therapy device, a casing with a lamp housingthereon and a forward projection from the housing through which rays from a lamp may be projected, a bracket arm for supporting the casing, a funnel sleeve adjustably fitted over said projection and having on its outer end upwardly and down* wardly extending arms, a pair of light filter disks coaxially pivoted on the downwardly extending arm and having symmetrically arranged color filters therein for adjustment relative to each other and t0 the axis of projection through the projection and the sleeve, a rod secured to the upwardly extending arm and disposed above and beyond the disks, a latching bar mounted on the rod and engaging the disks to hold the same in adjusted position, and a projecting lens adjustably mounted on the rod in line with the said axis of projection.

In testimony whereof I ailix my signature. MAJOR BERTRAND DE JARNETTE.
